Specificatiers Patent. Patented July 25-, 1916,

Application filed October 23, 1914. Serial No. 868,161.

To all whom it may concern:

Be it known that I, MAUDE F. BACK, a

citizen of the United States, residing at from the car.

The invention furthermore consists in the lIHPI'OVEIIlBIltS in the parts and devices and in the novel combinations of the parts and devices as herein shown, described or claimed. 7

In the drawing forming a part of this specification, Figure 1 is a longitudinal vertical sectional view of a draft rigging, showing one embodiment of my improvements. Fig. 2 is a horizontal sectional view taken substantially on the line 2-2 of 'Fig. 1, and showing the gear under full buff, and Fig.

3 is a vertical sectional view taken substan-' tially on the line 33 of Fig. 1.

In said drawing, -10 denote the center sills or draft members, the same being in the form of channels having their flanges turned outwardly and united at the top by a horizontal plate 11. The bills 10-10 are slotted to receive therethrough upper and lower stationary keys 12-12, the keys being held in place and prevented from accidental removal by cotters 13. Mounted on each of said keys 12, and extending forwardly therefrom is a U-shaped yoke or loop 14, each comprising side arms 15 slottedto receive the key 12, and transversely extending portion 16. The yokes 1414 are spaced vertically and receive therebetween a third yoke 17, which is turned in the opposite clirection to the yokes 14 and is attached to the draw bar 18 by means of a coupler key 19, said key 19 extending through elongated slots 20 in the side arms 21 of the yoke 17 and also through elongated slots 22 in the sills 10. Mounted between the rear cross portion 23 of the yoke 17 and the cross por-" tions 1616 of the yoke 14, are-vertically extending front and rear followers 24 and 25 respectively, said followers being provided with integrally formed upper and lower bosses 2626, on which are mounted inner springs 2727, said springs 2727 being each nested within an outer heavier spring 28. The followers and springs are supported by means of a saddle plate 29 (see Fig. 3) which saddle plate is secured to the sills 1010 by bolts 30 and nuts 31. As will be understood, the lower spring 28 rests directly upon the saddle plate 29 and this spring in turn supports the inner spring 27,

which spring 27 being mounted on the lower set of bosses 26-26 supports the followers 24; and 25. The saddle plate also directly supports the followers.

The operation of the device is as fol- ,lows:Upon bufling or inward movement of the draw bar-17, the rear end 32 thereof engages the front face of the front follower 24, thereby forcing the latter inwardly and compressing the springs against the rear follower 25, which is prevented. from rearward movement on account of its engagement with the upper and lower rear stationary keys 12-42. As will be apparent, during the buffing or inward movement of the draw bar, the coupler key 19- is free to slide within the slots 20 of the arms of the yoke 17, as well as in the slots 22 of the center sills. Upon pulling on outward movement of the draw bar 18, the yoke 17 is pulled forwardly by the conpler key 19 and the rear .cross piece 23 of said yoke engages and pulls forwardly the rear follower 25 thereby compressing the springs between it and the front follower 24, which latter is held from forward -movement by its engagement with the cross portions 16-16 of the upper and lower stationary yokes l114. As will be under stood by those skilled in the art, the keys 12-12 act as rear stops under buff and the cross portions 16-16 of the upper and lower yokes serve as front stops under draft. It will furthermore be understood that the followers and springs may be taken down by merely removing the saddle plate 29 and if desired, the yokes 1t14 and 17 may also be removed by taking out the keys l2 and coupler key 19V I claim 1-. In a draft rigging, the combination with slotted draft sills, of three U shaped members, one of said members being adapted to-act as a yoke and slidable between-the other two of said members, two removable keys located one above the other and passing through slots in said sills and slots near the free ends of said two members, followers disposed within saidmembers, and-cushioning means between said followers, said two keys acting as one set of stops and said two members as the other set of stops, said followers and cushioning means being removable from below without removing any of said three U shaped members.

2. In a draft rigging, the combination with slotted draft sills, of three U shaped members arranged one above the other, the

nieanaa upper and lower of said members having their free ends extending rearwardly and the middle one of said members having its free ends extended forwardly and adapted to -be connected to a drawbar, upper and lower horizontal keys extending through slots in said sills and slots near the free ends of said upper and lower U shaped members, and shock absorbingmechanism mounted within said members, said keys forming the rear stops and the transverse portions of said upper and lower U shaped members forming the front stops, said shock absorbing mechanism being removable from below.
